- Numbers n such that n and the four successive integers produce primes if substituted for x in the polynomial 5x^2+5x+1. See A090562, A090563. Terms show that longer similar chains also exist.at n=37A090100
- Numbers whose fifth powers are closer to cubic numbers than square numbers.at n=7A117594
- Numbers that are the same upside down (using only digits 0, 1, 6 and 9).at n=42A169731
- Numbers n such that n^5 and a cube are between consecutive squares.at n=20A173341
